Substitution of wildcards
by Jan Rheinländer 12 Jun '17

12 Jun '17

Hi, I'm wondering what is going on here (ginsh output): > subs($1 * x + 1/2 * x^2 * $2, match(a * x + b, $1 + x * $2)); b*a+1/2*a^3 What happened to "x" ? The match by itself correctly finds > match(a * x + b, $1 + x * $2); {$2==a,$1==b} but the substitution result is weird. Greetings, Jan

Best way to iterate through an expression
by Jan Rheinländer 11 May '17

11 May '17

Hi, my code has a lot of statements of this kind: if (is_a<mul>(some_ex)) { for (const auto& m : some_ex) { // Do something with m } } else { // Do something with some_ex } Is there a more elegant way of iterating through an expression that avoids having to write the "Do something" part twice? Thanks, Jan
